		bool	_passToNextStage,
		QString	_inputPrefix = "outVertex",

	)

Perform name matching of outputs and inputs between two shader stages.

IO of this shader (for instance fragment-shader) and its previous shader (for instance vertex shader) require matching names. Example: The vertex shader has an output "out vec3 outVertexNormal", then this function simply adds the input "in vec3 outVertexNormal" to the current shader (either a geometry or fragment shader). If this is a geometry shader, _passToNextStage should be set to true so that "out vec3 outGeometryNormal" is also added to the outputs.

Parameters

_previousShaderStage	shader of the previous stage, which should have all outputs setup already
_passToNextStage	all outputs of the previous shader stage are passed to the next stage (should be false for fragment shader for instance)
_inputPrefix	name prefix of inputs to this shader (only necessary if _passToNextStage is true)
_outputPrefix	name prefix of outputs of this shader (only necessary if _passToNextStage is true)
